Books: typical dorky stuff (Neal Stephenson, Charles Stross, Vernor
Vinge), Mountains Beyond Mountains (dude is awesomely inspiring),
The Devil in the White City, Brave New World, Millennium Trilogy
(and other such time-killing books; why not?), .... currently
enqueued: The Box. Somebody also recommended Einstein's Clocks,
Poincare's Maps, but it became less interesting halfway
Movies: oh, whatever's on: comedy, action, drama. I probably only
go to the theater once or twice a year lately (e.g. new Bond
movie), and I don't have Netflix or TV, so I mostly watch movies on
planes (e.g. latest Bourne) or at my friends' place (e.g.
Moneyball) or with my dad, who loves even terrible movies (e.g. In
Time) and then making fun of them for months thereafter.
Music: recent Pandora stations include Grimes, Hole, Holy Fuck,
MGMT, Passion Pit, Phoenix, The Killers, Tom Petty, Lana Del Rey,
Ratatat, Gotan Project, Bran Van 3000, Rhett Miller, Modest Mouse,
Built To Spill, The Submarines, Kanye, Grillz, .... okay, this is
all over the place.
Shows: I just saw Sleep No More! Holy crap--- most bizarrely
awesome experience ever. I can't recommend it highly enough. I've
been raving it about it for weeks now to anybody who will listen,
just as people did to me. So worth it.
Oh, TV shows: seems like the typical things, when I'm in a TV mood:
Arrested Development, Mad Men, True Blood, Game of Thrones, Grimm,
Daily Show / Colbert Report, etc. I don't have cable so I download
shows and try to run on my rainy-day-treadmill to make up for the
guilt of watching TV.
